BACKGROUND OF THE INVENTION

The present invention generally relates to task processing.

Traditionally, single-threaded systems are limited by how fast each itemcan be processed. Further, in processing workflows, with some systems,an error later in the workflow can leave the system in an inconsistentstate, or can cause loss of data.

Additionally, scaling traditional systems can be difficult. Physicalservers must be shut down to add resources. Virtual machines can scaleup (add resources), but traditional systems wouldn't allow scaling out(adding nodes).

A need exists for improvement in task processing. This need, as well asother needs, is addressed by one or more aspects of the presentinvention.

DETAILED DESCRIPTION

As a preliminary matter, it will readily be understood by one havingordinary skill in the relevant art (“Ordinary Artisan”) that the presentinvention has broad utility and application. As should be understood,any embodiment may incorporate only one or a plurality of theabove-disclosed aspects of the invention and may further incorporateonly one or a plurality of the above-disclosed features. Furthermore,any embodiment discussed and identified as being “preferred” isconsidered to be part of a best mode contemplated for carrying out thepresent invention. Other embodiments also may be discussed foradditional illustrative purposes in providing a full and enablingdisclosure of the present invention. As should be understood, anyembodiment may incorporate only one or a plurality of theabove-disclosed aspects of the invention and may further incorporateonly one or a plurality of the above-disclosed features. Moreover, manyembodiments, such as adaptations, variations, modifications, andequivalent arrangements, will be implicitly disclosed by the embodimentsdescribed herein and fall within the scope of the present invention.

Accordingly, while the present invention is described herein in detailin relation to one or more embodiments, it is to be understood that thisdisclosure is illustrative and exemplary of the present invention, andis made merely for the purposes of providing a full and enablingdisclosure of the present invention. The detailed disclosure herein ofone or more embodiments is not intended, nor is to be construed, tolimit the scope of patent protection afforded the present invention,which scope is to be defined by the claims and the equivalents thereof.It is not intended that the scope of patent protection afforded thepresent invention be defined by reading into any claim a limitationfound herein that does not explicitly appear in the claim itself.

Thus, for example, any sequence(s) and/or temporal order of steps ofvarious processes or methods that are described herein are illustrativeand not restrictive. Accordingly, it should be understood that, althoughsteps of various processes or methods may be shown and described asbeing in a sequence or temporal order, the steps of any such processesor methods are not limited to being carried out in any particularsequence or order, absent an indication otherwise. Indeed, the steps insuch processes or methods generally may be carried out in variousdifferent sequences and orders while still falling within the scope ofthe present invention. Accordingly, it is intended that the scope ofpatent protection afforded the present invention is to be defined by theappended claims rather than the description set forth herein.

Additionally, it is important to note that each term used herein refersto that which the Ordinary Artisan would understand such term to meanbased on the contextual use of such term herein. To the extent that themeaning of a term used herein—as understood by the Ordinary Artisanbased on the contextual use of such term—differs in any way from anyparticular dictionary definition of such term, it is intended that themeaning of the term as understood by the Ordinary Artisan shouldprevail.

Regarding applicability of 35 U.S.C. §112, ¶6, no claim element isintended to be read in accordance with this statutory provision unlessthe explicit phrase “means for” or “step for” is actually used in suchclaim element, whereupon this statutory provision is intended to applyin the interpretation of such claim element.

Furthermore, it is important to note that, as used herein, “a” and “an”each generally denotes “at least one,” but does not exclude a pluralityunless the contextual use dictates otherwise. Thus, reference to “apicnic basket having an apple” describes “a picnic basket having atleast one apple” as well as “a picnic basket having apples.” Incontrast, reference to “a picnic basket having a single apple” describes“a picnic basket having only one apple.”

When used herein to join a list of items, “or” denotes “at least one ofthe items,” but does not exclude a plurality of items of the list. Thus,reference to “a picnic basket having cheese or crackers” describes “apicnic basket having cheese without crackers”, “a picnic basket havingcrackers without cheese”, and “a picnic basket having both cheese andcrackers.” Finally, when used herein to join a list of items, “and”denotes “all of the items of the list.” Thus, reference to “a picnicbasket having cheese and crackers” describes “a picnic basket havingcheese, wherein the picnic basket further has crackers,” as well asdescribes “a picnic basket having crackers, wherein the picnic basketfurther has cheese.”

Referring now to the drawings, one or more preferred embodiments of thepresent invention are next described. The following description of oneor more preferred embodiments is merely exemplary in nature and is in noway intended to limit the invention, its implementations, or uses.

In one or more preferred implementations, a system utilizes queues,queue listeners, and tasks to implement a methodology. In one or morepreferred implementations, such a methodology can be characterized asutilizing dependency inversion.

In an exemplary methodology, for each step of a workflow, there is aqueue listener. This listener periodically polls an incoming queue fortasks. When a task is found, the item is generally marked as inprogress, the task is executed, a resulting task is placed in anoutgoing queue, and finally the task is removed from the incoming queue.The next step of the workflow treats the previous outgoing queue as itsincoming queue, and the process continues. If an error occurs, the taskwill, after a timeout, be re-pulled to try again. If a task fails acertain number of times, the task is preferably added to a failurerepository (e.g. to be examined by a support team). In one or morepreferred implementations, because the tasks are stored in persistentqueues and current state is stored with the task, new server instancescan be created to process items on the fly. In one or more preferredimplementations, if certain steps of the workflow require minimalresources, the queue listeners for different queues are started on thesame server (potentially at the cost of losing the ability to scalesteps individually).

For illustrative purposes, consider an exemplary process comprising foursteps, as illustrated in FIG. 1. In an exemplary implementation, a queuewill be set up for each of these steps, as illustrated in FIG. 2.

In one or more preferred implementations, one or more queue listenersperiodically poll a step queue for a task that needs to be performed(e.g. an instance of that step). In one or more preferredimplementations, queue listener may be configured to only poll a singlestep queue, while in one or more preferred implementations a queuelistener may be configured to poll multiple step queues.

When a task is found, the task is generally marked as in progress, thetask is executed, and a resulting task is placed into a subsequentqueue, as illustrated in FIG. 2. This process can be repeated for eachstep.

In one or more preferred implementations, rather than execute a taskitself, listener may be configured to assign a task to a worker, asillustrated in FIG. 3. In one or more preferred implementations, aworker may return a result to the listener who may pass it on to anotherqueue, as illustrated in FIG. 3, or the worker itself may pass a resultto another queue, as illustrated in FIG. 4.

In one or more preferred implementations, upon completion of a task,confirmation that the task has been completed is returned to the queuethe task came from, as illustrated in FIG. 5. For example, in one ormore preferred implementations, a task is indicated to be in progressonce it has been sent to a listener, and is then marked completed andremoved from the queue once confirmation has been received that the taskhas been completed. In one or more preferred implementations, ifconfirmation of completion is not received for a task that has been sentto a listener without a defined time frame, then the task is consideredto have failed to be completed and is placed back in the queue forsending out to another listener.

Additionally or alternatively, in one or more preferred implementations,a listener that fails to complete a task may communicate a failuremessage back to a queue, as illustrated in FIG. 6. The failure messagemay include an indication of the task that failed to be completed or acopy of the task itself. In one or more preferred implementations,repeated failures of a task may cause the task to be placed into afailure repository, as illustrated in FIG. 7.

In one or more preferred implementations, tasks are stored in persistentqueues and a current state is stored with the task, as illustrated inFIG. 8. The use of persistent queues and the storage of state dataallows listeners to pick up discrete tasks and process themindependently of other tasks, which in turn allows a system to be scaledout by adding additional listeners if needed. FIGS. 9-11 illustrate useof several listeners to process tasks of a persistent queue. Theselisteners may be running on separate servers, as illustrated in FIG. 12,or on the same server, as illustrated in FIG. 13.

Although thus far described in the context of a linear process forillustrative purposes, it will be appreciated that methodologiesdescribed herein are applicable to more complicated processes as well.For example, FIG. 14 illustrates use of four queues for a slightly morecomplicated process where processing of tasks received at each queue mayresult in various possible results. At any given time, each of thesequeues may have various numbers of tasks ready to be sent to a listener,as illustrated in FIG. 15. In one or more preferred implementations, ifone or more queues appear to be highly loaded, one or more additionallisteners may be brought into the system.

It will be appreciated that methodologies described herein may beutilized in implementing much more complicated processes. Forillustrative purposes, a methodology for use in a health care contextwill now be described.

Specifically, in one or more preferred implementations, methodologiesdescribed herein are utilized in a health care context to process healthcare workflows. In one or more preferred implementations, a methodologyfor processing health care workflows is implemented for a Windows Azureenvironment.

When a patient is receiving medical treatment, he or she may sometimesbe presented with a care plan which will facilitate his or hertreatment. The care plan may include instructions for one or moreactions to perform or measurements to take outside of a health careprofessional's supervision. For example, a patient may be provided acare plan which includes instructions to weigh himself or herself everyday, and record the results for eventual review by a health careprofessional.

Additionally, sometimes, a patient may be presented with a health caregoal to meet. For example, a patient may be instructed to try to meetthe goal of losing ten pounds over three months. This goal may includerelated instructions for the patient to weigh himself or herself everymorning.

In one or more preferred implementations, methodologies disclosed hereinare implemented for a monitoring and compliance application whichimproves patient engagement and collaboration between a patient and hisor her health care provider. In an exemplary methodology, orders arecreated in an EHR for patients to perform home monitoring. The patientis notified of the order and the request will appear as a goal for thepatient within a platform portal (such as, for example a web portal or amobile application). The patient may comply with the order (which mightbe, for example, to monitor his or her weight daily) utilizing wirelessdevices (such as a Withings scale) that can communicate data to otherdevices or to the platform, or by manually entering values into theplatform. This home monitoring data is then evaluated against patientspecific rules that were configured when the order was placed.Non-compliance of the order or violation of any of the order parameterswill result in a notification that is sent back to the ordering provideras a message in the EHR. The notification provides summary informationabout the order and results allowing the provider to determine if anintervention is necessary. Upon completion of the order, a summary ofthe results is sent back to the EHR for review by the provider.

FIG. 16 illustrates an exemplary methodology for analyzing a health careorder specified by a health care provider.

Systems and methodologies in accordance with one or more preferredimplementations described herein support parallel processing of items(e.g. tasks). Further, systems and methodologies in accordance with oneor more preferred implementations described herein support both scalingup and scaling out. For example, in accordance with one or morepreferred implementations, resources can be added to existing servers,or new servers can be added. Additionally, each step of a workflow canbe individually scaled.
